## Prerequisites

MmGdbusCall requires GObject.

## Known Implementations

MmGdbusCall is implemented by MMCall, MmGdbusCallProxy and MmGdbusCallSkeleton.

## Description

This section contains code for working with the org.freedesktop.ModemManager1.Call D-Bus interface in C.

## Functions

### mm_gdbus_call_get_direction ()

    gint
    mm_gdbus_call_get_direction (MmGdbusCall *object);

Gets the value of the "Direction" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

[skip]

#### Parameters

object | A MmGdbusCall. |

#### Returns

The property value.

### mm_gdbus_call_get_number ()

    const gchar *
    mm_gdbus_call_get_number (MmGdbusCall *object);

Gets the value of the "Number" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `mm_gdbus_call_dup_number()` if on another thread.

[skip]

#### Parameters

object | A MmGdbusCall. |

#### Returns

The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object` .

[transfer none][nullable]

### mm_gdbus_call_dup_number ()

    gchar *
    mm_gdbus_call_dup_number (MmGdbusCall *object);

Gets a copy of the "Number" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

[skip]

#### Parameters

object | A MmGdbusCall. |

#### Returns

The property value or `NULL` if the property is not set. The returned value should be freed with `g_free()`.

[transfer full][nullable]

### mm_gdbus_call_get_state ()

    gint
    mm_gdbus_call_get_state (MmGdbusCall *object);

Gets the value of the "State" D-Bus property.

[skip]

#### Parameters

object | A MmGdbusCall. |

#### Returns

The property value or `NULL` if the property is not set. The returned value should be freed with `g_variant_unref()`.

                                         gpointer user_data);

Asynchronously invokes the `LeaveMultiparty()` D-Bus method on `proxy` . When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from (see `g_main_context_push_thread_default()`). You can then call `mm_gdbus_call_call_leave_multiparty_finish()` to get the result of the operation.

See `mm_gdbus_call_call_leave_multiparty_sync()` for the synchronous, blocking version of this method.

#### Parameters

proxy | A MmGdbusCallProxy. |
cancellable | A GCancellable or `NULL`. | [nullable]
callback | A GAsyncReadyCallback to call when the request is satisfied or `NULL`. |
user_data | User data to pass to `callback` . |

                                    GError **error);

Finishes an operation started with `mm_gdbus_call_call_leave_multiparty()`.

#### Parameters

proxy | A MmGdbusCallProxy. |
res | The GAsyncResult obtained from the GAsyncReadyCallback passed to `mm_gdbus_call_call_leave_multiparty()`. |

                                    GError **error);

Synchronously invokes the `LeaveMultiparty()` D-Bus method on `proxy` . The calling thread is blocked until a reply is received.

#### Parameters

proxy | A MmGdbusCallProxy. |
cancellable | A GCancellable or `NULL`. | [nullable]

## Signal Details

### The `“dtmf-received”` signal

    void
    user_function (MmGdbusCall *object,
                   gchar       *arg_dtmf,
                   gpointer     user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "DtmfReceived" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A MmGdbusCall. |
arg_dtmf | Argument. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“handle-accept”` signal

    gboolean
    user_function (MmGdbusCall           *object,

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Accept()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `mm_gdbus_call_complete_accept()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A MmGdbusCall. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Signal emitted when a remote caller is invoking the `Deflect()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `mm_gdbus_call_complete_deflect()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A MmGdbusCall. |
invocation | A GDBusMethodInvocation. |
arg_number | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `JoinMultiparty()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `mm_gdbus_call_complete_join_multiparty()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run.
